Omastar (Revamp) [QC 3/3] (GP 2/2)



http://www.smogon.com/bw/pokemon/omastar/uber

[Overview]

<p>Due to Omastar's extremely low base 55 Speed stat, one might wonder why it should be considered in Ubers when there are much faster Swift Swim sweepers available. However, Omastar's rain-boosted and Choice Specs-boosted Hydro Pump has more power than any other move available to another Swift Swim sweeper, as it can OHKO Arceus after Stealth Rock. In addition, Omastar's secondary Rock typing and excellent base 125 Defense stat allow it to check Extreme Killer Arceus and Life Orb Ho-Oh, two Pokemon that are extremely difficult to check offensively otherwise, effectively in rain. Although Omastar's low base Speed might be a deterrent at first, Omastar still reaches 418 Speed in the rain, which is enough for it to outrun the likes of Darkrai, Mewtwo, and Shaymin-S and OHKO them before they have a chance to strike. Omastar also gets Shell Smash, an excellent boosting move that it can use to end the game, given that it is able to set up and has hazard support. Unfortunately, Omastar does have its weak points. Unlike Kingdra and Kabutops, Omastar is outsped by almost all of the Choice Scarf users commonly seen in Ubers, making it relatively easy to revenge kill. Omastar also struggles to deal with rain stall teams unless it has significant hazard support, as it does not have a diverse movepool. Lastly, Omastar is almost completely useless if Kyogre's rain is removed by an enemy weather setter. Do not let these drawbacks deter you from discounting the fossil as a threat; Omastar's combination of power and Speed makes it a deadly threat that every team needs to prepare for.</p>

[SET]
name: Choice Specs
move 1: Hydro Pump
move 2: Ice Beam
move 3: Surf
move 4: Earth Power / Hidden Power Rock
item: Choice Specs
nature: Modest
ability: Swift Swim
evs: 4 HP / 252 SpA / 252 Spe

[SET COMMENTS]

<p>This set allows Omastar to hit incredibly hard without suffering from Life Orb recoil. Although this Omastar cannot switch moves, it can check threats such as Ho-Oh, Extreme Killer Arceus, and Swords Dance Ghost Arceus extremely effectively in rain, as it can OHKO all three of them. Omastar can also accomplish feats such as 2HKOing max HP Grass Arceus and Water Arceus after Stealth Rock, and 2HKOing Blissey after Stealth Rock and one layer of Spikes. Hydro Pump is the main move Omastar will use early- to mid-game to ensure that it punishes Ho-Oh switch-ins and secures the OHKOs and 2HKOs that Surf cannot. To demonstrate Hydro Pump's power, the move 2HKOes 48 HP Latias after it switches into Stealth Rock twice. Ice Beam easily 2HKOes Latias, usually 2HKOes Palkia after Stealth Rock, and hits the Giratina formes hard. Surf is recommended on the same set despite its redundant coverage, as it allows Omastar to serve as a somewhat reliable win condition late-game, when the enemy's team has been weakened to the point that Hydro Pump is no longer needed. Surf is still strong enough to OHKO Darkrai and Mewtwo, though prior damage is needed for it to KO Arceus. The last move depends on personal preference. Earth Power smacks Dialga and Tentacruel for good damage and can OHKO offensive Dialga after Stealth Rock. However, Hidden Power Rock guarantees the 2HKO on Palkia after Stealth Rock and allows Omastar to check Ho-Oh in any weather, provided the phoenix does not carry Earthquake.</p>

[ADDITIONAL COMMENTS]

<p>As there are not many Pokemon with Speed stats between those of Mewtwo and Omastar in the rain, Omastar can often afford to run some HP EVs to take hits from Ho-Oh a little easier. However, do not run more than 40 HP EVs on Omastar, in order to ensure that it will outrun Adamant and Modest Deoxys-A in rain. Alternatively, one can choose to run more Speed on Omastar by utilizing a Timid nature, as doing so allows it to outrun uninvested base 90s even outside of rain. In the rain, Omastar will outspeed neutral-natured Choice Scarf Pokemon with base 90 Speed as well as Naive Deoxys-A. The loss of power is noticeable, though, as Timid Omastar cannot OHKO Arceus after Stealth Rock. Omastar's movepool is pretty barren, but Hidden Power Grass can be used in the fourth moveslot to destroy Gastrodon, which otherwise walls this set, and hit Kyogre and Water Arceus reliably.</p>

<p>Kyogre is required as a teammate in order to use Omastar in Ubers, as the rain it provides gives a boost to Omastar's Speed and Water-type moves. Though Kyogre and Omastar share checks such as Latias and Ferrothorn, they can easily power through them together. Calm Mind Ghost Arceus is a great teammate for Omastar, being able to spinblock the hazards Omastar needs to secure OHKOs and 2HKOs and set up on Choice Scarf Terrakion as it attempts to revenge kill the fossil with Close Combat. In return, Omastar can revenge kill Darkrai and switch into Ho-Oh, two of the best checks to Ghost Arceus. Other bulky Calm Mind Arceus formes also appreciate Omastar's ability to beat opposing Arceus and Ho-Oh. Ferrothorn makes a good partner for Omastar as well, despite the fact that it is also weak to Rayquaza and Fighting-type moves. Ferrothorn can easily take on most Choice Scarf users that bother Omastar and proceed to set up Spikes. In return, Omastar destroys Ho-Oh and can easily absorb Fire-type attacks aimed at Ferrothorn. Landorus-T can switch in on Choice Scarf Zekrom and Choice Scarf Terrakion for Omastar. It can also serve as a nice switch-in to Groudon and Tyranitar due to its Ground / Flying typing, Intimidate, and ability to threaten them with a powerful Earthquake. Lastly, specially defensive Grass Arceus can handle Kyogre and Kingdra, both of which Omastar struggles with.</p>

<p>Though Choice Specs Omastar can fit on all rain teams, it functions especially well on rain stall teams alongside Ferrothorn and Tentacruel. This is because it can severely damage offensive sun teams that include Ho-Oh, which teams with Ferrothorn and Tentacruel usually struggle against. Whenever rain is up, Omastar can come in on Ho-Oh and Swords Dance Arceus formes and spam Hydro Pump, which is very likely to knock out an opposing Pokemon. Unlike with Kabutops, Groudon cannot come in on Omastar, or else it risks taking massive damage. Specially defensive Groudon is easily 2HKOed by Ice Beam and Hydro Pump, while offensive Groudon is cleanly OHKOed. If Groudon is sacrificed to stop Omastar's rampage, the opponent loses the weather war and your chances of winning increase dramatically so long Kyogre is still alive. Due to Omastar's lack of reliable recovery, it cannot come in on Life Orb Ho-Oh more than twice. As a result, physically defensive Giratina-O makes a good partner for Omastar on rain stall teams, as it can take two Brave Birds from Ho-Oh and has a useful immunity to Earthquake.</p>

[SET]
name: Life Orb
move 1: Hydro Pump / Surf
move 2: Ice Beam
move 3: Shell Smash / Toxic Spikes / Spikes
move 4: Earth Power / Hidden Power Grass
item: Life Orb
nature: Modest
ability: Swift Swim
evs: 4 HP / 252 SpA / 252 Spe

[SET COMMENTS]

<p>This set eschews the extra power that Choice Specs brings in favor of the ability to switch moves and utilize either Shell Smash or entry hazards. Hydro Pump is Omastar's best move and deals heavy damage to any Pokemon that doesn't resist it. Hydro Pump no longer OHKOes bulky Extreme Killer Arceus after Stealth Rock, but it still does around 80% on average. Surf can be used over Hydro Pump for its consistency, but the decrease in power is noticeable. Ice Beam is needed to deal solid damage to Giratina, Grass Arceus, and Latias. Earth Power 2HKOes Dialga and Tentacruel but hits little else, whereas Hidden Power Grass defeats Gastrodon.<p>

<p>Omastar can run Shell Smash to double its Speed and Special Attack in one turn, making it extremely difficult to wall and impossible to revenge kill without priority. With Stealth Rock and one layer of Spikes, the only Pokemon that can take any of Omastar's common moves are specially defensive Water Arceus, specially defensive Kyogre, Ludicolo, Abomasnow, Chansey, and Jynx. Depending on whether Omastar runs Earth Power or Hidden Power Grass, either Tentacruel or Gastrodon can stop it as well. It is sufficient to say that if Omastar is able to get off a Shell Smash, chances are that it will sweep. The trick is to find an opportunity for Omastar to set up, as Omastar's overall bulk is poor by Ubers standards. Forretress and Leftovers Ho-Oh are examples of Pokemon that Omastar can set up a Shell Smash on. Even with proper team support, Omastar will not always find an opportunity to use Shell Smash, but it can still check Pokemon like Ho-Oh. If Shell Smash is not appealing, Omastar can also utilize entry hazards, as it has access to all three. However, it should only run one type of entry hazard, as it will rarely be able to set more than one layer in a match. Hazards can punish switches nicely if the opponent still has a healthy Omastar check, such as Kyogre. If you already have a Spikes user, Toxic Spikes are preferred. If you don't, though, Spikes are often more helpful; it depends on your team's needs.</p>

[ADDITIONAL COMMENTS]

<p>On the Shell Smash set, Hydro Pump and Surf can be used together in lieu of an additional coverage move. Although running both moves adds to the list of Pokemon that can combat Omastar after a Shell Smash, Omastar becomes more consistent, as it can choose either the raw power of Hydro Pump or the accuracy of Surf. If you want Omastar to function as an all-out attacker, a set consisting of Hydro Pump, Surf, Ice Beam, and either Earth Power or a Hidden Power is ideal. Hidden Power Rock is another option, as it can 2HKO Palkia after Stealth Rock, but it does not provide much additional coverage.</p>

<p>If Omastar runs Shell Smash, there are teammates available that can help it attain a boost. Dragon Dance Rayquaza can bait Choice Scarf Genesect's Ice Beam, which Omastar can easily set up a Shell Smash on. Mixed Dragon Dance Rayquaza can also break down walls that bother Omastar, such as Ferrothorn, while Omastar can switch into Swords Dance Arceus that try to set up on Rayquaza. Shaymin-S also baits Ice Beam from Choice Scarf Pokemon, as it threatens to flinch teams to death if it is not revenge killed. Bear in mind that Ice Beam is not the only Choice-locked move Omastar can set up on. If the opponent lacks priority moves, Omastar can take an attack such as a Stone Edge from Terrakion or an Outrage from any Choice Scarf-wielding Dragon-type in the tier and proceed to set up. Omastar can set up with ease on any Choice-locked Fire-type moves, although it is unlikely that your opponent will be using them in the rain. Wobbuffet can work well as a partner, as if it Encores the opponent into the right move, Omastar can get a free setup opportunity.</p>

<p>Regardless of whether or not Omastar runs Shell Smash, the same teammates that apply to the Choice Specs set also apply here. Ferrothorn and Omastar only share a weakness to Fighting-type moves and can take care of each other's checks. Bulky Calm Mind Arceus formes such as Fighting Arceus and Grass Arceus appreciate Omastar's ability to handle Ho-Oh. In return, they can deal with most of the Choice Scarf users that attempt to revenge kill the shellfish. Timid Life Orb Dialga is an intriguing teammate, as it can deal with the weather setters that Omastar is weak to, and resists Electric- and Grass-type moves. A Ghost-type such as Ghost Arceus or Giratina can provide a reliable switch-in to Choice Scarf Terrakion.</p>

[OTHER OPTIONS]

<p>Omastar's movepool is barren outside of the options already listed. Blizzard is usable on the Choice Specs set as it does a minimum of 76% to Latios, KOing it after it switches into Stealth Rock twice, and 2HKOes specially defensive Giratina. However, Blizzard's terrible accuracy means that Ice Beam is almost always a better option. If Omastar runs Shell Smash, a +2 Wring Out hits Palkia and Kyogre very hard if they are at or near full health. However, this is extremely situational and Omastar can break through most Kyogre and all Palkia with entry hazard support anyway. AncientPower can be used if you are feeling lucky, but Hidden Power Rock's higher Base Power makes it a more reliable option. Lastly, Stealth Rock can be used on the Life Orb set if you do not already have a Stealth Rock user.</p>

[Checks and Counters]

<p>Though Omastar hits hard, it is far from uncounterable. Specially defensive Kyogre can easily tank two Choice Specs-boosted Hydro Pumps and OHKO Omastar with Scald. Gastrodon walls any set lacking Hidden Power Grass, but needs to be careful when switching in unless you are sure that Omastar does not carry the move. Ludicolo hard-counters all Omastar sets and threatens to OHKO it with a Grass-type STAB move. Palkia can take a +2 Life Orb Omastar's Ice Beam and possesses a 4x resistance to Water-type moves, but is hit hard by Hidden Power Rock and Choice Specs-boosted Ice Beam. Ferrothorn with Power Whip can take two Hydro Pumps and OHKO Omastar in return, but it must be at full strength when it switches in, as Hydro Pump hits it quite hard. The same applies to Abomasnow, which can act as a one-time check to Omastar, but can get worn down quickly by a combination of Omastar's attacks and Stealth Rock damage. Specially defensive Water Arceus and Grass Arceus can take on Omastar as well, but max HP Arceus formes will often fall to two consecutive Hydro Pumps after Stealth Rock even if they resist the attack. Chansey and Blissey can switch into Omastar as long as their side of the field is clear of hazards. Specially defensive Giratina is only 2HKOed by the rare Blizzard from the Choice Specs set, but cannot damage Omastar much in return. Kingdra and specially defensive Latias are also decent checks that can threaten to OHKO Omastar, but neither likes taking an Ice Beam. Two additional Pokemon can counter most Omastar sets, though both are very niche. Vaporeon can tank anything, even two consecutive Hidden Power Grasses, and hit Omastar hard with Scald. Jynx cannot handle the uncommon Hidden Power Rock but easily takes any of Omastar's other moves and can quickly recover health with Dry Skin.</p>

<p>Checking Omastar offensively is significantly harder than checking it defensively, due to Omastar's naturally high Defense and resistance to ExtremeSpeed. Still, Choice Scarf users and Hasty Deoxys-A can revenge kill Omastar by preying on its low Special Defense stat. Do note, though, that Omastar Speed ties with neutral nature Choice Scarf base 90s. Choice Band Scizor can deal massive damage to Shell Smash Omastar due to the move's Defense dropping effect, as well as pick off a weakened one. Be aware that priority generally isn't enough to defeat Omastar, and you will need at least one dedicated check to prevent it from doing major damage to your team.</p>

[Overview]

-Water/Rock typing and reasonable 70/125 physical bulk make it an excellent check to Ho-Oh and Swords Dance Arceus formes
-Choice Specs Hydro Pump in the rain is an extremely powerful move, coming off 418 Speed
-Access to Shell Smash makes it a fearsome sweeper if it can set up on a predicted switch or a Choice-locked move such as Ice Beam
-Hits as hard, if not harder than other Swift Swimmers
-Outruns and OHKO's Darkrai and Mewtwo under rain
-Unlike other Swift Swimmers, it is slower than almost all Choice Scarf users commonly found in Ubers
-Like other Swift Swimmers, borderline useless if rain isn't up
-Struggles with rain stall if it lacks hazard support
-Mediocre movepool
-Overall a strong Pokemon with enough power to be viable in Ubers, even if it forgo's Shell Smash

[SET]
name: Choice Specs
move 1: Hydro Pump

move 3: Surf
move 4: Earth Power / Hidden Power Rock
item: Choice Specs
nature: Modest
ability: Swift Swim
evs: 4 HP / 252 SpA / 252 Spe

[SET COMMENTS]

-Hits brutally hard without suffering from Life Orb recoil; Hydro Pump does 85-100% to 252/0 Arceus and 2HKO's offensive Kyogre
-Can 2HKO heavy Water resists such as Grass Arceus and Ferrothorn if given hazard support (only needs Stealth Rock for max HP Grassy) while acting as a great Ho-Oh and EKiller check
-Hydro Pump is its main move and punishes anything that doesn't resist it
-Ice Beam 2HKO's Palkia that try to check it after Stealth Rock while mauling the Lati twins
-Surf is for consistently and for cleaning late game; it destroys Darkrai, Mewtwo, and weakened Arceus
-Earth Power deals severe damage to offensive Dialga, usually OHKOing it after Stealth Rock
-Hidden Power Rock can be used to beat Earthquake-less Ho-Oh in any weather while OHKOing the Kyurem formes after Stealth Rock (also hits Shedinja lol)

[ADDITIONAL COMMENTS]

-Can afford to run some HP to take hits a little better, but at least outrun Mewtwo (run 40 HP max)
-Timid allows it to outrun outside of rain, useful against Groudon...power loss is significant though and you are better off running Specs Kingdra if Speed is important to you
-It and Kyogre share checks, but can easily team up and overwhelm them
-Hidden Power Grass destroys Gastrodon and Quagsire, but has little use otherwise since Hydro deals almost as much damage to Kyogre and Water Arceus under rain
-Kyogre is obviously needed for rain, but arguably its 2nd best teammate is Ferrothorn, which can easily take on Kingdra/Choice Scarf users that try to revenge Omastar and use them as Spikes fodder while Omastar can take on Ho-Oh and Swords Dance EKiller and Ghost Arceus
-Calm Mind Ghost Arceus is another great partner for spinblocking the hazards Omastar likes to help it breaks down pokemon it lures in while laughing at Scarf Terrakion's attempts to revenge to fossil
-Specially Defensive Grass Arceus can be used with Omastar to handle Kingdra and Kyogre
-This set is surprisingly good on rain stall, due to its ability to check Ho-Oh & excellent synergy with Ferrothorn
-Groudon CANNOT switch in on this, offensive ones will be OHKO'd in the process while even Specially Defensive ones get whacked for massive damage

[SET COMMENTS]

-Eschews extra power from Choice Specs in favor of the ability to switch moves and utilize either Shell Smash or hazards
-Hydro Pump no longer OHKO's max HP Arceus after Stealth Rock, but still does massive damage
-Ice Beam is mandatory for Latias and Giratina formes
-With proper team support, Shell Smash is viable and turns Omastar into a fearsome sweeper with just one turn of set-up
-Alternatively, it can run a surprise hazards set since it has access to Spikes and Toxic Spikes
-Final move is filler, Earth Power hits Dialga and Tentacruel hard while Hidden Power Grass is nice for Gastrodon

[ADDITIONAL COMMENTS]

-Hydro Pump and Surf can be used on same set for consistency (I know Hack uses this)
-+2 Hidden Power Rock can OHKO Palkia after Stealth Rock
-Rayquaza and Shaymin-S make excellent teammates for Shell Smash users as they can lure Scarfed Ice Beams
-Wobbuffet also pairs well with Smash, potentially Encoring the opponent into an undesirable move while removing pesky Pokemon such as Choice Scarf Palkia
-Life Orb Max Speed Dialga destroys enemy weather setters and resists most of Omastar's weaknesses
-Giratina-O and Ghost Arceus handle Scarf Terrakion
-Ferrothorn checks Scarf Kyogre and Scarf Dragons

I would have thought that shell smasg gave omastar its niche 0_o
Anywho, you mention hp grass both in ac and oo.
I'd mention that hp rock reliably hits lugia outside rain but that's quite w/e.
Just my two cents, feel free to disagree ^_^
edit-oops just saw that youll put the smash set
 
Nah, Omastar is viable in Ubers even without the Smash. I'm not sure which set should go first to be honest. I removed the HP Grass comment from AC, God that section is bare.

Lugia Roost stalls Omastar outside of Rain unfortunately :(.
 
Specs first slash for sure. I also wanted you to redo the Shell Smash write-up because of lines like
Shell Smash is the crux of the set
and also because I was thinking of changing Shell Smash to just Life Orb where you could slash things like hazards/coverage with SS. Also, those revenge killer mentions bother me a lot when you don't RK the only speed booster in the metagame and you are reliant on weather to outspeed shit, anyways.

I agree with Melee Mewtwo about the Shell Smash set. I feel like actually managing to Shell Smash is incredibly difficult (especially if your opponent has seen that Omastar is carrying a Life Orb and can relatively safely assume that it is running Shell Smash), and most of the time the move would be better off having been replaced. While the Specs set has obvious advantages as an all-out attacker, I still see it as a viable option for a Life Orb set (alongside a mention of Spikes/Toxic Spikes).

Also, in the second paragraph of the Additional Comments of the Shell Smash set, I assume it means to say "the former deserves a special mention"; dual screens, not Wobbuffet, negate the defense drops.
 
Mention Abomasnow and other weather changers in Checks and Counters. The pink blobs can take Omastar's attacks easily. You might as well mention Jynx if you are going to bring up Vaporeon when I'm the only one who uses it. :p Besides that, there are some places where you repeat information that's in OO like Blizzard that's also AC on Specs (keep blizzard in OO) and hazards which are in LO. (so take those out of OO)

This has everything so QC Approved 1/3




Now, just outside of QC. I've noticed that Ferrothorn is cool with Omastar but it really adds to that Rayquaza weakness and Groudon can annoy both of them as well, so from personal experience I didn't feel like it was one of the best partners. (although, tbh, these problems are going to show up with just about any of the bulky steels you pair with Omastar) Also, I liked bulky CM Arceus formes in general with Omastar as it's pretty much the only really offensive mon (as in brilliant at punishing switches) that can check Ho-Oh. Landorus-T I found to be pretty sexy for that general utility of pivoting on the other weather mons but also because it helps check Terrakion and any fast Zekrom. This isn't part of QC, just me sharing my experiences so you add whatever you want if any at all.
 

polop

Would you look at the time?

Priority can be used as a last resort attempt to stop omastar (especially the smash set b/c defense drops) so I feel that should get some mention. Add Deo-a as a check since Naive or Hasty Deo-a outspeeds and OHKOes Omastar, given its modest. Timid lets it outspeed Deo-a all the time which I feel should be mentioned when you address it in AC of Specs.

When you mention it being good on rain stall, mention it can provide an awkward sort of win condition. The minute that the opposing weather setter + revenge killers fall due to hazards / repeated hydro pump spam is the minute Omastar cleans the rest of the team. This severely hurts the hopes of any of those last mon boosters that try to win against stall (they can't do that b/c Oma's spamming strong Hpumps when they come in).

Aside that Mewtwo got everything else I wanted to say.

QC Approved: 2/3

In Sweep we trust :P. Good job.
 
252+ SpA Choice Specs Omastar Hydro Pump vs. 4 HP / 252+ SpD Eviolite Chansey in rain: 207-244 (32.24 - 38%) -- guaranteed 3HKO after Stealth Rock and Spikes

You 2HKO the OU spread not the Ubers one. I also feel like it's worth mentioning that 48 HP Latias is 2HKO'd by Hydro Pump if it's already switched into SR once before, plus the fact that it's going to be used to check the Kyogre alongside Omastar means you will typically be in a scenario where Hydro Pump 2HKOs.

Omastar speed ties with max speed, neutral Scarf 90s.

For the Landorus-T mention, I feel like you should also bring up how effective it is at pivoting on TTar and Donner as it can, more or less, (thinking lava plume) safely switch in on the two while threatening them with his strong Earthquakes and get switch advantage with U-turn. (word that better than I do lol)

Though Choice Specs Omastar can fit on all team archetypes
I feel like it's worth specifying that it fits on all rain team archetypes, makes it sound like you can stick Omastar on sun, lol. (or maybe that's just me)

It also kinda bothers me you use the term rain stall for what you actually mean by FerroCruel cores. (cause there are a lot of variants of rain stall and not all of them are sun offense weak, some are the exact opposite) I guess the same thing applies for sun offense which you mean ho-oh sun offense.

shake it off!
This analysis has been in copyediting for a while now, so I've decided to work on an amcheck! I should have this done by tomorrow at the latest.

One issue that I've noticed so far deals with KOes vs. KOs:
  • OHKOes as the verb form (Salamence OHKOes Alakazam) and OHKOs as a plural noun (Salamence scores many OHKOs). OHKOed is the past tense (Salamence OHKOed Alakazam).

Earth Power 2HKOs Dialga --> Earth Power 2HKOes Dialga
Giratina is only 2HKO'd by the rare Blizzard --> Giratina is only 2HKOed by the rare Blizzard

Other than that, everything looks pretty good in general!

shake it off!
Amcheck! I think the analysis is very well written, and I hope this helps!

Palkia can take a +2 Life Orb Omastar's Ice Beam and OHKO it back while possessing a 4x resistance to water moves, but gets hits hard by Hidden Power Rock and Specs Ice Beam.
I was wondering if the bolded move should be Hydro Pump, since Choice Specs Omastar's Ice Beam is weaker than a +2 Life Orb Omastar's Ice Beam.

Removals

[Overview]

<p>Due to Omastar's extremely low base 55 Speed stat, one may wonder why it should be considered in Ubers when there are much Swift Swim sweepers available. However, Omastar's Choice Specs and rain-boosted Hydro Pump has more power than any other move available to another Swift Swim sweeper, as it can OHKO Arceus after Stealth Rock. In addition, Omastar's secondary Rock typing and excellent base 125 Defense stat allow it to check Extreme Killer Arceus and Life Orb Ho-Oh effectively in rain, two Pokemon that are extremely difficult to check offensively otherwise. Though Omastar's low base Speed may be a deterrent at first, Omastar still reaches 418 Speed in the rain, which is enough for it to outrun the likes of Darkrai, Mewtwo, and Shaymin-S and OHKO them before they have a chance to strike. Omastar also gets Shell Smash, an excellent boosting move that it can use to end the game, given that it is able to set up and has hazard support. Unfortunately, Omastar does have its weak points. Unlike Kingdra and Kabutops, Omastar is outsped by almost all of the Choice Scarf users commonly seen in Ubers, making it relatively easy to revenge kill. Omastar also struggles to deal with rain stall teams unless it has significant hazard support, as it does not have a diverse movepool. Lastly, Omastar is almost completely useless if Kyogre's rain is removed by an enemy weather setter. Do not let these drawbacks deter you from discounting the fossil as a threat; Omastar's combination of power and speed makes it a deadly threat that every team needs to prepare for.</p>

[SET]
name: Choice Specs
move 1: Hydro Pump
move 2: Ice Beam
move 3: Surf
move 4: Earth Power / Hidden Power Rock
item: Choice Specs
nature: Modest
ability: Swift Swim
evs: 4 HP / 252 SpA / 252 Spe

[SET COMMENTS]

<p>This set allows Omastar to hit incredibly hard without suffering from Life Orb recoil. While this Omastar cannot switch moves, it can check threats such as Ho-Oh, Extreme Killer Arceus, and Swords Dance Ghost Arceus extremely effectively in rain, as it can OHKO all three of them. Omastar can also accomplish feats such as 2HKOing max HP Grass Arceus and Water Arceus after Stealth Rock, and 2HKOing Blissey after Stealth Rock and one layer of Spikes. Hydro Pump is the main move Omastar will use early to mid-game to ensure that it punishes Ho-Oh switch-ins and secures OHKOs and 2HKOs. To demonstrate Hydro Pump's power, the move 2HKOes 48 HP Latias after it switches into Stealth Rock twice. Ice Beam easily 2HKOes Latias, usually 2HKOes Palkia after Stealth Rock, and hits the Giratina formes hard. Surf is recommended on the same set despite its redundant coverage, as it allows Omastar to serve as a somewhat reliable win condition late-game, when the enemy's team has been weakened to the point that Hydro Pump is no longer needed. Surf is still strong enough to OHKO Darkrai and Mewtwo, though prior damage is needed for it to KO Arceus. The last move depends on personal preference. Earth Power smacks Dialga and Tentacruel for good damage and can OHKO offensive Dialga after Stealth Rock. However, Hidden Power Rock guarantees the 2HKO on Palkia after Stealth Rock and allows Omastar to check Ho-Oh in any weather, provided the phoenix does not carry Earthquake.</p>

[ADDITIONAL COMMENTS]

<p>As there are not many Pokemon with Speed stats between those of Mewtwo and Omastar in the rain, Omastar can often afford to run some HP EVs to take hits from Ho-Oh a little easier. However, do not run more than 40 HP EVs on Omastar, in order to ensure that it will outrun Adamant and Modest Deoxys-A in rain. Alternatively, one can choose to run more Speed on Omastar by utilizing a Timid nature, as doing so allows it to outrun uninvested base 90s even outside of rain. In the rain, Omastar will outspeed neutral nature Choice Scarf Pokemon with base 90 Speed as well as Naive Deoxys-A. The loss of power is noticeable though, as Timid Omastar cannot OHKO Arceus after Stealth Rock. Omastar's movepool is pretty barren, but Hidden Power Grass can be used in the fourth moveslot to destroy Gastrodon, which otherwise walls this set, and hit Kyogre and Water Arceus reliably.</p>

<p>Kyogre is required as a teammate in order to use Omastar in Ubers, as the rain it provides gives a boost to Omastar's Speed and Water-type moves. Though Kyogre and Omastar share checks such as Latias and Ferrothorn, they can easily power through them together. Calm Mind Ghost Arceus is a great teammate for Omastar, being able to spinblock the hazards Omastar needs to secure OHKOs and 2HKOs and set up on Choice Scarf Terrakion as it attempts to revenge kill the fossil with Close Combat. In return, Omastar can revenge kill Darkrai and switch into Ho-Oh, two of the best checks to Ghost Arceus. Other bulky Calm Mind Arceus formes also appreciate Omastar's ability to beat opposing Arceus and Ho-Oh. Ferrothorn also makes a good partner for Omastar, despite the fact that it is also weak to Rayquaza and Fighting-type moves. Ferrothorn can easily take on most Choice Scarf users that bother Omastar and proceed to set up Spikes. In return, Omastar destroys Ho-Oh and can easily absorb Fire-type attacks aimed at Ferrothorn. Landorus-T can switch in on Choice Scarf Zekrom and Choice Scarf Terrakion for Omastar. It can also serve as a nice switch-in to Groudon and Tyranitar due to its Ground / Flying typing, Intimidate, and ability to threaten them with a powerful Earthquake. Lastly, specially defensive Grass Arceus can handle both Kyogre and Kingdra, both of which Omastar struggles with.</p>

<p>Though Choice Specs Omastar can fit on all rain teams, it functions especially well on rain stall teams alongside Ferrothorn and Tentacruel. This is because it can severe damage offensive sun teams that include Ho-Oh, which teams with Ferrothorn and Tentacruel usually struggle against. Whenever rain is up, Omastar can come in on Ho-Oh and Swords Dance Arceus formes and spam Hydro Pump, which is very likely to knock out an opposing Pokemon. Unlike with Kabutops, Groudon cannot come in on Omastar, or else it risks taking massive damage. Specially defensive Groudon is easily 2HKOed by Ice Beam and Hydro Pump, while offensive Groudon is cleanly OHKOed. If Groudon is sacrificed to stop Omastar's rampage, the opponent loses the weather war and your chances of winning increase dramatically so long Kyogre is still alive. Due to Omastar's lack of reliable recovery, it cannot come in on Life Orb Ho-Oh more than twice. As a result, physically defensive Giratina-O makes a good partner for Omastar on rain stall teams, as it can take two Brave Birds from Ho-Oh and has a useful immunity to Earthquake.</p>

[SET COMMENTS]

<p>This set eschews the extra power that Choice Specs brings in favor of the ability to switch moves and utilize either Shell Smash or entry hazards. Hydro Pump is Omastar's best move and deals heavy damage to any Pokemon that doesn't resist it. Hydro Pump no longer OHKOes bulky Extreme Killer Arceus after Stealth Rock, but it still does around 80% on average. Surf can be used over Hydro Pump for its consistency, but the decrease in power is noticeable. Ice Beam is needed to deal solid damage to Giratina, Grass Arceus, and Latias. Earth Power 2HKOes Dialga and Tentacruel but hits little else, whereas Hidden Power Grass defeats Gastrodon.<p>

<p>Omastar can run Shell Smash to double its Speed and Special Attack in one turn, making it extremely difficult to wall and impossible to revenge kill without priority. With Stealth Rock and one layer of Spikes, the only Pokemon that can take any of Omastar's common moves are specially defensive Water Arceus, specially defensive Kyogre, Ludicolo, Abomasnow, Chansey, and Jynx. Depending on whether Omastar runs Earth Power or Hidden Power Grass, either Tentacruel or Gastrodon can stop it as well. It is sufficient to say that if Omastar is able to get off a Shell Smash, chances are that it will sweep. The trick is to find an opportunity for Omastar to set up, as Omastar's overall bulk is poor by Ubers standards. Forretress and Leftovers Ho-Oh are examples of Pokemon that Omastar can set up a Shell Smash on. Even with proper team support, Omastar will not always find an opportunity to use Shell Smash, but it can still check Pokemon like Ho-Oh. If Shell Smash is not appealing, then Omastar can also utilize entry hazards, as it has access to all three. However, it should only run one type of entry hazard, as it will rarely be able to set more than one layer in a match. Hazards can punish switches nicely if the opponent still has a healthy Omastar check, such as Kyogre. If you already have a Spikes user, Toxic Spikes are preferred. If you don't though, Spikes are often more helpful–it depends on your team's needs.</p>

[ADDITIONAL COMMENTS]

<p>On the Shell Smash set, Hydro Pump and Surf can be used together in lieu of an additional coverage move. Though running both moves adds to the list of Pokemon that can combat Omastar after a Shell Smash, Omastar becomes more consistent, as it can choose either the raw power of Hydro Pump or the accuracy of Surf. If you want Omastar to function as an all-out attacker, then it can run a set consisting of Hydro Pump, Surf, Ice Beam, and either Earth Power or a Hidden Power. Hidden Power Rock is another option, as it can 2HKO Palkia after Stealth Rock, but it does not provide much additional coverage.</p>

<p>If Omastar runs Shell Smash, there are teammates available that can help it attain a boost. Dragon Dance Rayquaza can bait Choice Scarf Gensect's Ice Beam, which Omastar can easily set up a Shell Smash on. Mixed Dragon Dance Rayquaza can also break down walls that bother Omastar, such as Ferrothorn, while Omastar can switch into Swords Dance Arceus that try to set up on Rayquaza. Shaymin-S also baits Ice Beams from Choice Scarf Pokemon, as it threatens to flinch teams to death if it is not revenge killed. Bear in mind that Ice Beam is not the only Choice-locked move Omastar can set up on. If the opponent lacks priority moves, Omastar can take an attack such as a Stone Edge from Terrakion or an Outrage from any Choice Scarf Dragon-type in the tier and proceed to set up. Omastar can set up with ease on any Choice-locked Fire-type moves, although it is unlikely that your opponent will be spamming them in the rain. Wobbuffet can work well as a partner, because if it Encores the opponent into the right move, Omastar can get a free setup opportunity.</p>

<p>Regardless of whether or not Omastar runs Shell Smash, the same teammates that applied to the Choice Specs set also apply here. Ferrothorn and Omastar only share a weakness to Fighting-type moves and can take care of each other's checks. Bulky Calm Mind Arceus formes such as Fighting Arceus and Grass Arceus appreciate Omastar's ability to handle Ho-Oh. In return, they can deal with most of the Choice Scarf users that attempt to revenge kill the shellfish. Timid Life Orb Dialga is an intriguing teammate, as it can deal with the weather setters that Omastar is weak to, and resists Electric- and Grass-type moves. A Ghost-type such as Ghost Arceus or Giratina can provide a reliable switch-in to Choice Scarf Terrakion.</p>

[OTHER OPTIONS]

<p>Omastar's movepool is barren outside of the options already listed. Blizzard is usable on the Choice Specs set as it does a minimum of 76% to Latios, KOing it after it switches into Stealth Rock twice, and 2HKOes specially defensive Giratina. However, Blizzard's terrible accuracy means that Ice Beam is almost always a better option. If Omastar runs Shell Smash, a +2 Wring Out hits Palkia and Kyogre very hard if they are at or near full health. However, this is extremely situational and Omastar can break through most Kyogre and all Palkia with entry hazard support anyway. AncientPower can be used if you are feeling lucky, but Hidden Power Rock's higher Base Power makes it a more reliable option. Lastly, Stealth Rock can be used on the Life Orb set if you do not already have a Stealth Rock user.</p>

[Checks and Counters]

<p>Though Omastar hits hard, it is far from uncounterable. Specially defensive Kyogre can easily tank two Choice Specs-boosted Hydro Pumps and OHKO Omastar with Scald. Gastrodon walls any set lacking Hidden Power Grass, but needs to be careful when switching in unless it is sure that Omastar does not carry the move. Ludicolo hard counters all Omastar sets and threatens to OHKO it with a Grass-type STAB move. Palkia can take a +2 Life Orb Omastar's Ice Beam and possesses a 4x resistance to Water-type moves, but is hit hard by Hidden Power Rock and Choice Specs-boosted Ice Beam. Ferrothorn with Power Whip can take two Hydro Pumps and OHKO Omastar in return, but it must be at full strength when it switches in as Hydro Pump hits it quite hard. The same applies to Abomasnow, which can act as a one-time check to Omastar, but it can get worn down quickly by a combination of Omastar's attacks and Stealth Rock damage. Specially defensive Water Arceus and Grass Arceus can take on Omastar as well, but max HP Arceus formes will often fall to two consecutive Hydro Pumps after Stealth Rock even if they resist the attack. Chansey and Blissey can switch into Omastar so long their side of the field is clear of hazards. Specially defensive Giratina is only 2HKOed by the rare Blizzard from the Choice Specs set, but cannot damage Omastar much in return. Kingdra and specially defensive Latias are also decent checks that can threaten to OHKO Omastar, but neither likes taking an Ice Beam. Two additional Pokemon can counter most Omastar sets, though both are very niche. Vaporeon can tank anything, even two consecutive Hidden Power Grasses, and hit Omastar hard with Scald. Jynx cannot handle the uncommon Hidden Power Rock but easily takes any of Omastar's other moves and can quickly recover health with Dry Skin.</p>

<p>Checking Omastar offensively is significantly harder than checking it defensively, due to Omastar's naturally high Defense and resistance to ExtremeSpeed. Still, Choice Scarf users and Hasty Deoxys-A can revenge kill Omastar by preying on its low Special Defense stat. Do note though, that Omastar Speed ties with neutral nature Choice Scarf base 90s. Choice Band Scizor can deal massive damage to a boosted Shell Smash Omastar as well as pick off a weakened one. Be aware that priority generally isn't enough to defeat Omastar, and you will need at least one dedicated check to prevent it from doing major damage to your team.</p>


[Overview]

<p>Due to itOmastar's extremely low 55 base 55 Speed stat, one may wonder why Omastarit should be considered in Ubers when there are much faster Pokemon that carry Swift Swim sweepers available. However, Omastar's Choice Specs and Rrain-boosted Hydro Pump has gmoreater power than any other move available to another Swift Swimm sweeper, as it possesses the power tocan OHKO Arceus after Stealth Rock. In addition, Omastar's secondary Rock typing and excellent base 125 dDefense stat allows it to effectively check Extremek Killer Arceus and Life Orb Ho-Oh effectively in the rain, two Pokemon that are extremely difficult to check offensively check otherwise. Though Omastar's low base Speed may be a deterrent at first, Omastar still reaches 418 Speed in the rain, which is enough for it to outrun the likes of Darkrai, Mewtwo, and Shaymin-S and OHKO them before they have a chance to strike back. Omastar also gets Shell Smash, an excellent boosting move that it can use to end the game if Omastar, given that it is able to obtain a Smash boostset up and has hazard support. Unfortunately, Omastar does have its weak points. Unlike Kingdra and Kabutops, Omastar is outrunsped by almost all of the Choice Scarf users commonly seen in Ubers, making it relatively easy to revenge kill. Omastar also struggles to dental with rain stall teams unless it has significant hazard support, as it does not have a diverse movepool. FinalLastly, Omastar is almost completely useless if Kyogre's rain is removed by thean enemy weather setter. Do not let these drawbacks deter you from discounting the fossil as a threat; Omastar's combination of power and speed makes it a deadly threat that every team needs to prepare for.</p>

[SET COMMENTS]

<p>This set allows Omastar to hit incredibly hard without suffering from Life Orb recoil. While this Omastar set cannot switch moves, it can check threats such as Ho-Oh, Extremek Killer Arceus, and Swords Dance Ghost Arceus extremely effectively in rain because Omastar, as it can OHKO all three of them. Omastar can also accomplish feats such as 2HKOing max HP Grass Arceus and Water Arceus after Stealth Rock, and 2HKOing Blissey after Stealth Rock and one layer of Spikes. Hydro Pump is the main move Omastar will use early to mid-game to ensure that it punishes Ho-Oh switche-ins and secures OHKO's and 2HKO's. To demonstrate Hydro Pump's power, ithe move 2HKO'es 48 HP Latias after it switchinges into Stealth Rock twice. Ice Beam easily 2HKOes Latias and, usually 2HKO'es Palkia after Stealth Rock. It also, and hits the Giratina formes hard. Surf is recommended on the same set despite theits redundant coverage, as it can allows Omastar to serve as a somewhat reliable win condition late-game, when the enemy's team has been weakened to athe point wherethat Hydro Pump is no longer needs to be used. Surf is still strong enough to OHKO Darkrai and Mewtwo, though prior damage is needed to killfor it to KO Arceus with this move. The last move depends on personal preference. Earth Power smacks Dialga and Tentacruel for good damage and can actually OHKO offensive Dialga after Stealth Rock. However, Hidden Power Rock guarantees the 2HKO on Palkia after Stealth Rock whileand allowings Omastar to check Ho-Oh in any weather, provided ithe phoenix does not carry Earthquake.</p>

[ADDITIONAL COMMENTS]

<p>BecauseAs there are not many Pokemon with Speed stat runs between those of Mewtwo and Omastar in the rain, Omastar can often afford to run some healthHP EVs to take hits from Ho-Oh a little easier. However, do not run more than 40 HP EVs on Omastar, in order to ensure that it stwill outruns Adamant orand Modest Deoxys-A in the rain. Alternatively, one couldan choose to run more Speed on Omastar by utilizing a Timid nature. D, as doing so allows Omastarit to outrun uninvested base 90's even outside of rain while. In the rain, Omastar will outspeeding neutral nature base 90 Choice Scarf users andPokemon with base 90 Speed as well as Naive Deoxys-A in rain. However, tThe loss of power is noticeable though, as you no longerTimid Omastar cannot OHKO Arceus after Stealth Rock. Omastar's movepool is pretty barren, but Hidden Power Grass can be used in the 4fourth moveslot to destroy Gastrodon, (whoich otherwise walls this set) while reliably, and hitting Kyogre and Water Arceus reliably.</p>

<p>Kyogre is a required as a teammate int forder to usinge Omastar in Ubers, as the rain support it provides gives a boosts ito Omastar's Speed and Water-type moves. Though Kyogre and Omastar share checks, such as Latias and Ferrothorn, they can easily combine to overpower power through them togethemr. Calm Mind Ghost Arceus is a great teammate tofor Omastar, as it canbeing able to spinblock the hazards Omastar needs to secure OHKOs and 2HKOs while usingand set up on Choice Scarf Terrakion' as it attempts to revenge kill the fossil with Close Combat as a set-up opportunity. In return, Omastar can revenge kill Darkrai and switch into Ho-Oh, two of the best checks to Ghost Arceus in . Othe game. Br bulky Calm Mind Arceus forms other than Ghost also appreciate Omastar's ability to beat opposing Arceus and Ho-Oh. Ferrothorn also makes a good partner tofor Omastar, despite the fact that they share ait is also weak to Rayquaza and Fighting weakn-type movess. Ferrothorn can easily take on most Choice Scarf users that bother Omastar with ease anand proceed to set up Spikes on them. In return, Omastar again destroys Ho-Oh whileand can easily absorbing f Fire-type attacks aimed at Ferrothorn. Landorus-Therian can switch in on Choice Scarf Zekrom and Choice Scarf Terrakion for Omastar. It can also provideserve as a nice switch-in againsto Groudon and Tyranitar due to its Ground / Flying typing and, Intimidate, and ability to threaten them with a powerful Earthquake. FinalLastly, Sspecially Ddefensive Grass Arceus can handle both Kyogre and Kingdra, both of which Omastar struggles with.</p>

<p>Though Choice Specs Omastar can fit on all rain teams, it functions especially well on rain stall teams withalongside Ferrothorn and Tentacruel due to.

Thanks, implemented the corrections! +2 Ice Beam does more to Palkia than a +2 Hydro Pump though :p.

Edit: Specs Ice Beam 2HKOs Palkia after SR, but a +2 LO Ice Beam can never 2HKO Palkia :o

I know - I just think that saying that it lives a +2 LO Ice Beam and then saying it gets hit hard by a Specs Ice Beam sort of suggests that the latter is stronger. Hmmm... maybe it's just me?

<p>Due to Omastar's extremely low base 55 Speed stat, one may might wonder why it should be considered in Ubers when there are much faster Swift Swim sweepers available. However, Omastar's Choice Specs- and rain-boosted Hydro Pump has more power than any other move available to another Swift Swim sweeper, as it can OHKO Arceus after Stealth Rock. In addition, Omastar's secondary Rock typing and excellent base 125 Defense stat allow it to check Extreme Killer Arceus and Life Orb Ho-Oh effectively in rain, two Pokemon that are extremely difficult to check offensively otherwise, effectively in rain. Though Although Omastar's low base Speed may might be a deterrent at first, Omastar still reaches 418 Speed in the rain, which is enough for it to outrun the likes of Darkrai, Mewtwo, and Shaymin-S and OHKO them before they have a chance to strike.

While Although this Omastar cannot switch moves, it can check threats such as Ho-Oh, Extreme Killer Arceus, and Swords Dance Ghost Arceus extremely effectively in rain, as it can OHKO all three of them. Omastar can also accomplish feats such as 2HKOing max HP Grass Arceus and Water Arceus after Stealth Rock, and 2HKOing Blissey after Stealth Rock and one layer of Spikes. Hydro Pump is the main move Omastar will use early- to mid-game to ensure that it punishes Ho-Oh switch-ins and secures the previously OHKOs and 2HKOs (does surf get these? might be a good idea to say no other stab move can do this, otherwise.) To demonstrate Hydro Pump's power, the move 2HKOes 48 HP Latias after it switches into Stealth Rock twice. Ice Beam easily 2HKOes Latias, usually 2HKOes Palkia after Stealth Rock, and hits the Giratina formes hard. Surf is recommended on the same set despite its redundant coverage, as it allows Omastar to serve as a somewhat reliable win condition late-game, when the enemy's team has been weakened to the point that Hydro Pump is no longer needed. Surf is still strong enough to OHKO Darkrai and Mewtwo, though prior damage is needed for it to KO Arceus. The last move depends on personal preference. Earth Power smacks Dialga and Tentacruel for good damage and can OHKO offensive Dialga after Stealth Rock. However, Hidden Power Rock guarantees the 2HKO on Palkia after Stealth Rock and allows Omastar to check Ho-Oh in any weather, provided the phoenix does not carry Earthquake.</p>

The loss of power is noticeable,(AC) though, as Timid Omastar cannot OHKO Arceus after Stealth Rock. Omastar's movepool is pretty barren, but Hidden Power Grass can be used in the fourth moveslot to destroy Gastrodon, which otherwise walls this set, and hit Kyogre and Water Arceus reliably.</p>

<p>Kyogre is required as a teammate in order to use Omastar in Ubers, as the rain it provides gives a boost to Omastar's Speed and Water-type moves. Though Kyogre and Omastar share checks such as Latias and Ferrothorn, they can easily power through them together. Calm Mind Ghost Arceus is a great teammate for Omastar, being able to spinblock the hazards Omastar needs to secure OHKOs and 2HKOs and set up on Choice Scarf Terrakion as it attempts to revenge kill the fossil with Close Combat. In return, Omastar can revenge kill Darkrai and switch into Ho-Oh, two of the best checks to Ghost Arceus. Other bulky Calm Mind Arceus formes also appreciate Omastar's ability to beat opposing Arceus and Ho-Oh. Ferrothorn also makes a good partner for Omastar as well (repetition of 'also;), despite the fact that it is also weak to Rayquaza and Fighting-type moves. Ferrothorn can easily take on most Choice Scarf users that bother Omastar and proceed to set up Spikes. In return, Omastar destroys Ho-Oh and can easily absorb Fire-type attacks aimed at Ferrothorn. Landorus-T can switch in on Choice Scarf Zekrom and Choice Scarf Terrakion for Omastar. It can also serve as a nice switch-in to Groudon and Tyranitar due to its Ground / Flying typing, Intimidate, and ability to threaten them with a powerful Earthquake. Lastly, specially defensive Grass Arceus can handle Kyogre and Kingdra, both of which Omastar struggles with.</p>

<p>Though Choice Specs Omastar can fit on all rain teams, it functions especially well on rain stall teams alongside Ferrothorn and Tentacruel. This is because it can severely damage offensive sun teams that include Ho-Oh, which teams with Ferrothorn and Tentacruel usually struggle against. Whenever rain is up, Omastar can come in on Ho-Oh and Swords Dance Arceus formes and spam Hydro Pump, which is very likely to knock out an opposing Pokemon. Unlike with Kabutops, Groudon cannot come in on Omastar, or else it risks taking massive damage. Specially defensive Groudon is easily 2HKOed by Ice Beam and Hydro Pump, while offensive Groudon is cleanly OHKOed. If Groudon is sacrificed to stop Omastar's rampage, the opponent loses the weather war and your chances of winning increase dramatically so long Kyogre is still alive. Due to Omastar's lack of reliable recovery, it cannot come in on Life Orb Ho-Oh more than twice. As a result, physically defensive Giratina-O makes a good partner for Omastar on rain stall teams, as it can take two Brave Birds from Ho-Oh and has a useful immunity to Earthquake.</p>

[SET COMMENTS]

<p>This set eschews the extra power that Choice Specs brings in favor of the ability to switch moves and utilize either Shell Smash or entry hazards. Hydro Pump is Omastar's best move and deals heavy damage to any Pokemon that doesn't resist it. Hydro Pump no longer OHKOes bulky Extreme Killer Arceus after Stealth Rock, but it still does around 80% on average. Surf can be used over Hydro Pump for its consistency, but the decrease in power is noticeable. Ice Beam is needed to deal solid damage to Giratina, Grass Arceus, and Latias. Earth Power 2HKOes Dialga and Tentacruel but hits little else, whereas Hidden Power Grass defeats Gastrodon.<p>

<p>Omastar can run Shell Smash to double its Speed and Special Attack in one turn, making it extremely difficult to wall and impossible to revenge kill without priority. With Stealth Rock and one layer of Spikes, the only Pokemon that can take any of Omastar's common moves are specially defensive Water Arceus, specially defensive Kyogre, Ludicolo, Abomasnow, Chansey, and Jynx. Depending on whether Omastar runs Earth Power or Hidden Power Grass, either Tentacruel or Gastrodon can stop it as well. It is sufficient to say that if Omastar is able to get off a Shell Smash, chances are that it will sweep. The trick is to find an opportunity for Omastar to set up, as Omastar's overall bulk is poor by Ubers standards. Forretress and Leftovers Ho-Oh are examples of Pokemon that Omastar can set up a Shell Smash on. Even with proper team support, Omastar will not always find an opportunity to use Shell Smash, but it can still check Pokemon like Ho-Oh. If Shell Smash is not appealing, then Omastar can also utilize entry hazards, as it has access to all three. However, it should only run one type of entry hazard, as it will rarely be able to set more than one layer in a match. Hazards can punish switches nicely if the opponent still has a healthy Omastar check, such as Kyogre. If you already have a Spikes user, Toxic Spikes are preferred. If you don't,(AC) though, Spikes are often more helpful; (semi) it depends on your team's needs.</p>

[ADDITIONAL COMMENTS]

<p>On the Shell Smash set, Hydro Pump and Surf can be used together in lieu of an additional coverage move. Though Although running both moves adds to the list of Pokemon that can combat Omastar after a Shell Smash, Omastar becomes more consistent, as it can choose either the raw power of Hydro Pump or the accuracy of Surf. If you want Omastar to function as an all-out attacker, then it can run a set consisting of Hydro Pump, Surf, Ice Beam, and either Earth Power or a Hidden Power is ideal. Hidden Power Rock is another option, as it can 2HKO Palkia after Stealth Rock, but it does not provide much additional coverage.</p>

<p>If Omastar runs Shell Smash, there are teammates available that can help it attain a boost. Dragon Dance Rayquaza can bait Choice Scarf Genesect's Ice Beam, which Omastar can easily set up a Shell Smash on. Mixed Dragon Dance Rayquaza can also break down walls that bother Omastar, such as Ferrothorn, while Omastar can switch into Swords Dance Arceus that try to set up on Rayquaza. Shaymin-S also baits Ice Beam from Choice Scarf Pokemon, as it threatens to flinch teams to death if it is not revenge killed. Bear in mind that Ice Beam is not the only Choice-locked move Omastar can set up on. If the opponent lacks priority moves, Omastar can take an attack such as a Stone Edge from Terrakion or an Outrage from any Choice Scarf-wielding Dragon-type in the tier and proceed to set up. Omastar can set up with ease on any Choice-locked Fire-type moves, although it is unlikely that your opponent will be spamming using them in the rain. Wobbuffet can work well as a partner, because as if it Encores the opponent into the right move, Omastar can get a free setup opportunity.</p>

<p>Regardless of whether or not Omastar runs Shell Smash, the same teammates that applied apply to the Choice Specs set also apply here. Ferrothorn and Omastar only share a weakness to Fighting-type moves and can take care of each other's checks. Bulky Calm Mind Arceus formes such as Fighting Arceus and Grass Arceus appreciate Omastar's ability to handle Ho-Oh. In return, they can deal with most of the Choice Scarf users that attempt to revenge kill the shellfish. Timid Life Orb Dialga is an intriguing teammate, as it can deal with the weather setters that Omastar is weak to, and resists Electric- and Grass-type moves. A Ghost-type such as Ghost Arceus or Giratina can provide a reliable switch-in to Choice Scarf Terrakion.</p>

[OTHER OPTIONS]

<p>Omastar's movepool is barren outside of the options already listed. Blizzard is usable on the Choice Specs set as it does a minimum of 76% to Latios, KOing it after it switches into Stealth Rock twice, and 2HKOes specially defensive Giratina. However, Blizzard's terrible accuracy means that Ice Beam is almost always a better option. If Omastar runs Shell Smash, a +2 Wring Out hits Palkia and Kyogre very hard if they are at or near full health. However, this is extremely situational and Omastar can break through most Kyogre and all Palkia with entry hazard support anyway. AncientPower can be used if you are feeling lucky, but Hidden Power Rock's higher Base Power makes it a more reliable option. Lastly, Stealth Rock can be used on the Life Orb set if you do not already have a Stealth Rock user.</p>

[Checks and Counters]

<p>Though Omastar hits hard, it is far from uncounterable. Specially defensive Kyogre can easily tank two Choice Specs-boosted Hydro Pumps and OHKO Omastar with Scald. Gastrodon walls any set lacking Hidden Power Grass, but needs to be careful when switching in unless it is you are sure that Omastar does not carry the move. Ludicolo hard-counters all Omastar sets and threatens to OHKO it with a Grass-type STAB move. Palkia can take a +2 Life Orb Omastar's Ice Beam and possesses a 4x resistance to Water-type moves, but is hit hard by Hidden Power Rock and Choice Specs-boosted Ice Beam. Ferrothorn with Power Whip can take two Hydro Pumps and OHKO Omastar in return, but it must be at full strength when it switches in,(AC) as Hydro Pump hits it quite hard. The same applies to Abomasnow, which can act as a one-time check to Omastar, but it can get worn down quickly by a combination of Omastar's attacks and Stealth Rock damage. Specially defensive Water Arceus and Grass Arceus can take on Omastar as well, but max HP Arceus formes will often fall to two consecutive Hydro Pumps after Stealth Rock even if they resist the attack. Chansey and Blissey can switch into Omastar so as long as their side of the field is clear of hazards. Specially defensive Giratina is only 2HKOed by the rare Blizzard from the Choice Specs set, but cannot damage Omastar much in return. Kingdra and specially defensive Latias are also decent checks that can threaten to OHKO Omastar, but neither likes taking an Ice Beam. Two additional Pokemon can counter most Omastar sets, though both are very niche. Vaporeon can tank anything, even two consecutive Hidden Power Grasses, and hit Omastar hard with Scald. Jynx cannot handle the uncommon Hidden Power Rock but easily takes any of Omastar's other moves and can quickly recover health with Dry Skin.</p>

<p>Checking Omastar offensively is significantly harder than checking it defensively, due to Omastar's naturally high Defense and resistance to ExtremeSpeed. Still, Choice Scarf users and Hasty Deoxys-A can revenge kill Omastar by preying on its low Special Defense stat. Do note,(AC) though, that Omastar Speed ties with neutral nature Choice Scarf base 90s. Choice Band Scizor can deal massive damage to a boosted Shell Smash Omastar due to the move's Defense dropping effect, as well as pick off a weakened one. Be aware that priority generally isn't enough to defeat Omastar, and you will need at least one dedicated check to prevent it from doing major damage to your team.</p>

Don't use 'while' where you mean 'although'. Also, I saw that you made this mistake twice, but when you say something like "rain and Choice Specs-boosted" you mean "rain-boosted and Choice Specs-boosted" so the hyphen should be there for both. Not too many errors :)
GP 2/2!
